Setup and Preparation
For Hinge Mortising (A99HT3)
- Secure the Door: Ensure the door is stable and properly supported before beginning any work.
- Attach Hinge Template: Position the A99HT3 Hinge Template on the door edge where the hinge mortise is required. The template features an integrated screw-in clamp for secure attachment.
- Adjust Hinge Length Guide: Utilize the onboard adjustment tool and bit depth gauge to set the desired hinge length and routing depth. The template accommodates standard door thicknesses.
- Install Router Bit: Insert the provided carbide tip router bit into your router. Ensure it is securely fastened according to your router's instructions.

For Latch Mortising (A99LM2)
- Identify Latch Bore: Locate the center of the latch bore on the door edge. The guide post on the A99LM2 tool assists in this alignment.
- Select Scoring Blade: The A99LM2 features a reversible scoring blade for either round or square latches. Select the appropriate side by rotating the blade as needed.
- Position Tool: Place the A99LM2 tool against the door edge, aligning the guide post with the latch bore. Use the 90-degree fence to ensure proper perpendicular alignment.

Operating Instructions
Hinge Mortising with A99HT3
- Rout the Mortise: With the template securely clamped and the router bit installed, carefully rout the hinge mortise. Follow your router's instructions for safe operation, moving the router smoothly within the template.
- Check Depth: Use the bit depth gauge to ensure the mortise depth is correct for your hinge. Adjust the router depth as needed.
- Remove Template: Once routing is complete, allow the router to stop completely before removing it from the template. Then, unclamp and carefully remove the template from the door.
- Install Hinge: Use the self-centering hinge bit to pre-drill screw holes for the hinge. Then, secure the hinge into the mortise with screws using the PH2/8-10SL double-ended screwdriver bit.

Latch Mortising with A99LM2
- Score the Outline: With the A99LM2 tool positioned correctly, firmly tap the areas marked "Strike Here" with a hammer to score the outline of the latch plate. Ensure a clear, deep score.
- Chisel Out Wood: Use the integrated chisel tool to remove the scored wood. Align the chisel edge with the guide post and gently tap with a hammer to clear the mortise. Remove wood chips as you go.
- Install Latch: Once the mortise is clear and clean, place the latch into the prepared recess. Use the included 1-inch PH2 bit or 1-inch SL 8-10 bit with a drill or screwdriver to secure the latch with screws.

Maintenance
- Cleaning: After each use, clean both tools to remove wood dust and debris. Use a dry cloth or soft brush. Avoid harsh chemicals that may damage the plastic components.
- Storage: Store the tools and bits in a dry, protected area away from direct sunlight and extreme temperatures to prevent damage and corrosion.
- Bit Inspection: Regularly inspect the router bit, self-centering hinge bit, and driver bits for wear, dullness, or damage. Replace worn bits to maintain optimal performance and safety.
Troubleshooting
- Uneven Hinge Mortise: Ensure the A99HT3 template is securely clamped to the door and does not shift during routing. Verify the router bit depth is consistently set and maintained throughout the cut.
- Inaccurate Latch Mortise: Confirm the A99LM2 tool is aligned correctly with the latch bore and held firmly against the door edge during scoring. Ensure the correct scoring blade (round/square) is selected and properly engaged.
- Difficulty Chiseling: Ensure the initial scoring is deep enough to provide a clear outline for the chisel. Use gentle, controlled taps with a hammer, working gradually to remove wood.
